Name the countries of South America by order of their easternmost points of land including islands up to 100 feet in length. Claims south of 60ºS not included.

While online maps aren't known for precise accuracy, there are times when seconds count (ie slight errors made by surveyors). Although these may be approximations within an acceptable range of error, the precision is needed for differential purposes. South America is defined as south of the Panamanian border, Caribbean Islands belonging to predominately South American countries, the Galapagos, the Falklands, and South Georgia and South Sandwich Islands. I've combined four quizzes into one because with only fourteen countries on this continent, it seemed a waste not to.
